Videotape only has a limited resolution after all, its not like film where you can rescan to get a more detailed picture...
Say its a face - normal resizing would scale upwards, smoothly scaling the features without jagged edges, but blurry. AI would recognise its a face, with features like circles, curves, arcs,, and redraw these 'cleanly', recreating the resolution. It's particularly good on geometric shapes like CGI and text as they can be recreated mathematically much better.Thats a terrible explanation. Of course it can't recreate the same effect as 35mm, but some things can be very convincing.
